Okay, this is a long list and I'm half-asleep but here goes!
Desmond Miles (this journal) - Technically, he would be from this world were it not for something that happened four years ago SO he's an AU. (I don't want to spell out much now that Kristy is playing the series. XD) The important part is that Desmond is an assassin. His father is (I THINK?) the current Mentor of the worldwide brotherhood - I.E. the big honcho. They have a rocky ass history but they were doing better. He has a son that he's not aware of who would be 11 now. He's a Sage, so he'll have visions as an adult and is a big damn templar target. Desmond is cynical and snarky, but ultimately a heroic dude. He's a new arrival and will be an assassin field agent in NYC. Though he might take a freaking vacation for a bit IDK.
Ezio Auditore (canon) (mentore) - this is pretty much the same Ezio I have at Fairharbor except he's not with Jacob (SAD). He's been here since August and he's an Assassin field agent in NYC. He USED to be Mentor of the Italian Brotherhood so this was a fun adjustment. He does like modern advancements tho, so there's that. He's sort of serious and snarky (this is going to be a theme, sorry), but he's much more even-tempered and considerate in his "old age".
Ezia Auditore (genderswap) (assassina) - Genderswapped Ezio! She's from around the end of Assassin's Creed 2. She's a little more brutal and pragmatic, but also a little more wild than her canon counterpart. She's not in denial about her bisexuality so she flirts without shame. She's been here a month and is an assassin field agent in London.
Ezio Auditore (de-aged) (vendicativo) - 20 year old Ezio! He pretends super hard that he's got this shit handled and he only likes girls but both of these things are a big fat lie. He's only about 3 years removed from the death of his family, so he was still in full vengeance mode with hardly any real assassin training. He'll be a trainee field agent and ultimately an assassin field agent. He's new as of game start and will hang around NYC until I figure out where to put him.
Jesse McCree (Junkenstein AU) (itshighnoon) - McCree was part of a Van Helsing-esque Blackwatch until everybody started going darkside and then he went off on his own. He's easy going until you're an asshole and has his own code about which monsters deserve to die (i.e. he judges people on their actions). And I KNOW I should be using Van Helsing icons but meh. He looks like a cowboy with a mechanical arm even if there isn't really a cowboy equivalent in his weird frankenstein style world. He's been here since early september and he's an assassin field agent in NYC.
Jesse McCree (de-aged) (notquitenoon) - Jesse is canon, he's just 19. He's been with Blackwatch 2 years, so he's still learning how to be a badass, but he's got both his arms and he's pretty devoted to Gabriel Reyes. He's got a helluva lot less baggage than his canon age, so he'll be a smug little shit for the most part. He'll be living with de-aged Gabe and Jack in LA. I had him as a field agent trainee, but since Gabe is undercover, I moved him to undercover. He'll still do basic assassin training for a few weeks in NYC before he moves out to LA.
Commander Shepard (paragon vanguard canon) (goodshepard) - this is my Fairharbor Shepard only jumped forward about 7 months into Bethany's pregnancy. He's technically an assassin field agent in NYC, but he's been playing a more supportive role close to home lately and will probably through Bethany giving birth. He's a good guy, leader type, gallows humor. He's been here since November 2015 and he was my person who was taken by the templars and experimented on. (He came in broken and bleeding so it was a lot easier to capture him too.) On the plus side, he met Bethany in captivity! Yay hostage romance!
Porthos (Modern Kingsman!AU) (humanhurricane) - Porthos is from a modern AU where the Musketeers are spies ala Kingsman: The Secret Service. He is an undercover agent in NYC, but he's also an unofficial foster parent to misplaced kids of assassins. He's canon in personality - brave, bold, protective bear type. Loves a good joke and great wine.
Jefferson (Cursed!Killian!AU) (madasahatter) - Jefferson is from an Once Upon a Time AU were Killian was included in the curse. He was still "the mad hatter", but a little less of a complete hermit in his world. He's kind of a grumpy asshole, but under that he's got a great sense of humor and a damaged heart that just never recovered from failing and ultimately losing his daughter. He works as a black market agent in London and has been here since August.
Ana Amari (canon) (childrenbehave) - the same Ana I have at Fairharbor only this one had a good flirt going with Reinhardt back in the day, they just never acted on it. War sucks, etc. She's assassin support in NYC for now, and has a house with a few rooms available for overwatch types. She's been here since July.
Marian Hawke (female rogue canon) (unbroken) - Hawke is of the Circle!Bethany/Whit's Adaar world. She's a dual-weapon rogue who romanced Anders and then killed him when he showed he was a terrorist. She's snarky and a little callous and a lot impulsive. She guesses she'll be an assassin field agent eventually. She's new and hanging around NYC for now.
